Product details
Overview
JANTX1N6135 from Semtech is a transient diverting suppressor (TDS) designed for high-energy EOS protection on 22V-rated power or I/O lines, featuring ±30kV IEC 61000-4-2 ESD immunity, 40A peak pulse current (8/20μs), 27.5–28V clamping voltage at 40A, and 20mΩ dynamic resistance - deployed in USB Type-C PD input protection and industrial load switch front-end circuits.
For engineers reviewing the JANTX1N6135 datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, DFN-6 package layout guidance, temperature-stable clamping behavior, and direct alternatives for 22V bus protection in high-reliability embedded and industrial systems.
Technical Context
The JANTX1N6135 uses a surge-rated FET as its primary protection element, activated by a precision trigger circuit that turns on the shunt path when transient voltage exceeds breakdown. Unlike conventional TVS diodes, its clamping voltage remains nearly constant across 24–40A pulse currents due to decreasing RDS(on) under surge conditions.
It operates over –40°C to +125°C with stable 27.5–28V clamping at 40A (1.2/50μs + 8/20μs combination waveform, RS = 2Ω), 175pF junction capacitance at 22V/1MHz, and <600nA reverse leakage - enabling robust protection without thermal derating penalties typical of PN-junction TVS devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage | 22V - matches nominal USB PD bus and industrial 24V rail operating ranges without derating. |
| Clamping Voltage | 27.5–28V at 40A - stays below 30V damage threshold of common load switches and PD controllers. |
| Peak Pulse Current | 40A (8/20μs) - meets IEC 61000-4-5 Level 4 surge immunity for industrial equipment. |
| ESD Withstand | ±30kV contact & air (IEC 61000-4-2) - exceeds automotive and industrial ESD requirements. |
| Dynamic Resistance | 20mΩ - enables low-voltage overshoot during fast transients and minimizes power dissipation. |
| Junction Capacitance | 175pF at 22V/1MHz - compatible with DC-coupled 22V power rails; not suitable for high-speed data lines. |
| Operating Temp | –40°C to +125°C - supports extended-temperature industrial and automotive under-hood applications. |
Pinout & Package
Package: DFN 1.6mm × 1.6mm × 0.55mm, 6-lead, Pb-free, RoHS-compliant, UL 94V-0 molding compound. Thermal pad not required - energy dissipated in silicon during transient events.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 | GND | Common ground return for surge current; all three pins must be connected to maximize current handling and minimize inductance. |
| 4, 5, 6 | IN | Protected line input (e.g., VBUS or load switch VIN); parallel connection ensures uniform current sharing and optimal clamping performance. |
Key Features
| Feature | Design Value |
|---|---|
| FET-based shunt architecture | Enables flat clamping voltage vs. pulse current - avoids voltage runaway seen in standard TVS diodes. |
| Temperature-stable clamping | 27.5–28V clamping maintained from –40°C to +125°C - eliminates thermal derating calculations. |
| Low dynamic resistance | 20mΩ ensures minimal IR drop during 40A surges - critical for protecting sensitive downstream FETs. |
| High EFT immunity | ±4kV per IEC 61000-4-4 (5/50ns, 5kHz & 100kHz) - protects against repetitive burst noise in motor drives and PLCs. |
| Space-efficient packaging | 1.6mm × 1.6mm footprint saves >60% board area versus SO-8 or SOT-23 TVS solutions at same rating. |
Applications
| USB Type-C Power Delivery Protection | Industrial Load Switch Input Protection |
|---|---|
|
Use Scenario: Protecting VBUS lines in USB-C receptacles supporting up to 20V/5A PD negotiation. IC Role / Device Role / Timing Role: Primary EOS shunt suppressor placed between connector and PD controller or load switch input. Use Value: Maintains 27.5–28V clamping across full 40A surge range and temperature extremes - prevents latch-up or gate oxide damage in PD ICs. |
Use Scenario: Front-end protection for high-side load switches (e.g., HS2950P) in remote meters and robotics. IC Role / Device Role / Timing Role: Transient voltage clamp limiting input overshoot to protect internal MOSFET gate oxide and OVP circuitry. Use Value: 20mΩ dynamic resistance limits voltage spike to ≤28V even during 40A lightning-induced surges - avoids false OVP trips and device destruction. |
| IoT Edge Node Power Rail Protection | Industrial Equipment DC Bus Protection |
|
Use Scenario: Securing 22V auxiliary rails in battery-backed IoT gateways exposed to field ESD and induced surges. IC Role / Device Role / Timing Role: Single-device solution for IEC 61000-4-2/4-4/4-5 compliance on unregulated input paths. Use Value: ±30kV ESD + ±4kV EFT + 40A surge capability in one 1.6mm × 1.6mm package - reduces BOM count and layout complexity. |
Use Scenario: Protecting 24V DC distribution buses in programmable logic controllers and factory HMIs. IC Role / Device Role / Timing Role: High-energy clamping device installed at panel entry points before DC-DC converters and microcontrollers. Use Value: Stable 27.5–28V clamping across –40°C to +125°C eliminates need for derating curves - simplifies safety certification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDS2211P.C | Same die, commercial-grade version (–40°C to +85°C), identical electrical specs and pinout. | Not qualified for military/aerospace use; lacks JANTX screening and extended temp range. | Select JANTX1N6135 for MIL-PRF-19500/565-compliant programs requiring extended temperature and reliability screening. |
| SM712-TP | Bidirectional TVS diode array; 12V working voltage, 33V clamping at 20A; higher dynamic resistance (~0.5Ω). | Designed for RS-485/RS-232 data line protection - unsuitable for 22V power rail clamping. | Only consider for lower-voltage signal lines; JANTX1N6135 provides superior clamping stability and current handling for 22V power domains. |
Compared with TDS2211P.C and SM712-TP, JANTX1N6135 delivers military-grade temperature range (–55°C to +150°C storage), JANTX-level screening, and flat clamping performance essential for mission-critical 22V power rail protection - where commercial or signal-line TVS alternatives fall short in reliability and thermal margin.

FAQ
What is the maximum clamping voltage of JANTX1N6135 at 40A surge current?
The JANTX1N6135 clamps at 27.5–28V under 40A peak pulse current (1.2/50μs voltage + 8/20μs current combination waveform, RS = 2Ω). This value is guaranteed across –40°C to +125°C and reflects its FET-based architecture - unlike conventional TVS diodes, clamping does not rise with increasing current or temperature. The JANTX1N6135 maintains this performance without derating.
Does JANTX1N6135 require a thermal pad on the PCB?
No, JANTX1N6135 does not require a thermal pad. Its energy dissipation occurs within the silicon during transient events, and the DFN package is designed for direct mounting without thermal vias or copper pours beneath the body. Layout best practice is to connect all GND pins (1, 2, 3) to a solid ground plane using multiple vias - but no thermal pad is specified or needed for JANTX1N6135 operation.
Can JANTX1N6135 be used on high-speed data lines like USB SuperSpeed?
No, JANTX1N6135 is not suitable for high-speed data lines. With 175pF junction capacitance at 22V, it would severely degrade signal integrity on USB 3.x, PCIe, or DisplayPort interfaces. It is intended exclusively for DC-coupled power or low-frequency I/O lines (e.g., VBUS, CC, SBU, or load switch inputs). For data line protection, Semtech recommends RClamp3371ZC (<0.25pF) alongside JANTX1N6135 in full USB-C solutions.
What is the difference between JANTX1N6135 and commercial TDS2211P.C?
JANTX1N6135 is the military-screened version of the TDS2211P, qualified per MIL-PRF-19500/565 with extended temperature range (–55°C to +150°C storage), rigorous burn-in and life test requirements, and lot traceability. Electrically identical to TDS2211P.C, JANTX1N6135 adds reliability assurance for aerospace, defense, and critical industrial applications where commercial-grade parts are insufficient.
How should JANTX1N6135 be positioned on the PCB for optimal protection?
JANTX1N6135 must be placed as close as possible to the protected connector - ideally within 5mm - to minimize trace inductance and prevent transient coupling into adjacent nets. All three IN pins (4, 5, 6) must be tied together with a short, wide trace to the protected line, and all three GND pins (1, 2, 3) must connect directly to a low-inductance ground plane via multiple vias. This layout ensures JANTX1N6135 activates before downstream components see damaging overvoltage.
